FNES 163 NUTRITION EXAM 2 QUESTIONS AND
ANSWERS
BMR decreases with age ________ - CORRECT ANSWER✅✅3-5% per decade after the age of 30
Simple carbohydrates consist of - CORRECT ANSWER✅✅monosaccharides and disaccharides
monosaccharides consist of - CORRECT ANSWER✅✅only a single sugar molecule
(glucose,fructose,galactose,ribose)
Disaccharides consist of - CORRECT ANSWER✅✅2 molecules of sugar joined together ( lactose,
maltose,sucrose)
polysaccharides are - CORRECT ANSWER✅✅long chains of glucose molecules(starch, glycogen and most
fibers)
Complex carbohydrates consist of - CORRECT ANSWER✅✅polysaccharides
Carbohydrates - CORRECT ANSWER✅✅An important energy source for nerve cells (4kcal/gram)
Carbohydrates are composed of - CORRECT ANSWER✅✅the atoms carbon, hydrogen, and oxygen
Insulin is a - CORRECT ANSWER✅✅hormone secreted by the beta cells of pancreas (in the response to
increase blood levels of glucose *facillitates the uptake of glucose by body cells)
Function of Insulin - CORRECT ANSWER✅✅Stimulates the liver and muscles to take up glucose and
convert it to glycogen
If blood glucose levels are too high - CORRECT ANSWER✅✅the pancreas releases insulin to stimulate
the liver to release LESS glucose
, Glucagon is a - CORRECT ANSWER✅✅hormone secreted by alpha cells of pancreas (in response to
decreased blood levels go glucose
*****Causes the breakdown of liver stores of glycogen into glucose**)
glucose is stored as glycogen in - CORRECT ANSWER✅✅the liver and muscles (glycogenesis) and stored
as triglycerides in adipose tissue (lipogenesis)
insulin stimulates the storage of - CORRECT ANSWER✅✅glucose in the body
glycolysis is - CORRECT ANSWER✅✅glucagon stimulates liver to convert stored glycogen into the
glucose, which is released into the blood and transported to cells for energy
gluconeogenesis is - CORRECT ANSWER✅✅glucagon also assists in the breakdown of proteins and the
uptake of amino acids by the liver which creates glucose from amino acids
soluble fiber - CORRECT ANSWER✅✅dissolves in water and reduce risk for cardiovascular disease and
type 2 diabetes by lowering blood cholesterol and glucose levels
soluble fibers are found in - CORRECT ANSWER✅✅citrus foods, beans, oats, berries
insoluble fibers generally - CORRECT ANSWER✅✅do not dissolve in water and promote regular bowel
movements, alleviate constipation and reduce risk for diverticulosis
insoluble fibers are found in - CORRECT ANSWER✅✅whole grains and many vegetables
lipids do not - CORRECT ANSWER✅✅dissolve in water
3 classes of lipids are - CORRECT ANSWER✅✅triglyceride (fats and oils)
phospholipids
